Now in many reports on mobile Internet access, you can often see or hear a new technique of abbreviations GPRS. Most people still don't know much about this new thing, but in the near future, this thing will be like ISDN. Like WAP, you can understand it.
GPRS --- GeneralPacketRadioservice, universal wireless packet business, is a wireless packet switching technology based on GSM system, providing end-to-end, wide-area wireless IP connections. Popular speaking, GPRS is a high-speed data processing technology, and the method is to transmit information to the user in the form of "packet". Although GPRS is a transition technology evolved to third generation mobile communication as an existing GSM network, it has significant advantages in many ways. At present, Hong Kong has achieved good results in the region of the first GPRS field test.
Due to the use of "grouping" technology, users can access the pain of the disconnection (the situation is similar to the download software Netants). In addition, the method of using the GPRS Internet is different from WAP. It is like a WAP online, first "dial-up connection", and then use the phone line at the same time after the Internet, but GPRS is superior, download information and calls can be At the same time. From a technical phone, the sound transfer (ie, call) continues to use GSM, and the data is transmitted to use GPRS, so that the application of the mobile phone is upgraded to a higher level. And the development of GPRS technology is also very "economy" because it is only necessary to develop in existing GSM networks. GPRS is very wide, including sending and receiving emails through mobile phones, browsing on the Internet.
Now the slogan of the mobile phone is "alwaysonline", "iPinhand", after using GPRS, data implementation group sends and accepts, which means that users are always online and forth, and quickly reduce service costs. For China Mobile / Unicom WAP tariff policy continues to be in a non-productive state, if CSD (circuit exchange data, ie, the usual dial data, Eurasian WAP business uses the bearer mode) beared to implement on GPRS, It is common to do dozens of people to undertake the cost of one person.
The greatest advantage of GPRS is that its data transfer speed is not Map that WAP can match. The current transmission speed of the GSM mobile communication network is 9.6k bytes per second, and the GPRS phone has reached the transfer speed of 56kbps when launched this year. Nowadays, it is more than 115kbps (this speed is often used in the ideal rate of 56KMODEM). . So please invite everyone to cherish the Nokia7110 and Motorolal 2000 in his hand. I believe that when they have been launched, they have to let the road.
GPRS application, which will also cooperate with Bluetooth (Bluetooth technology). At that time, the digital camera adds Bluetooth, you can immediately pass the mobile phone, send the like a film to the distant place, but a time, cool, this day will be not far away. (Calm)
